The blow molding machine is designed to produce PET bottles from heated preforms by drawing and two-stage blow molding in a four-cavity mold. The machine consists of a power unit, a preform heating oven, a preform autoloader, and a container with a control terminal.
The volume of blown containers is from 0.25 to 2.0 liters. Real-time monitoring of the position of the units. An automatic system for maintaining the optimum operating temperature in the electrical cabinet is used. Automatic adaptation of equipment units to specified performance parameters.
Distinctive features:
- Reliable and well-thought-out design of PET blow molding machines ensures guaranteed safety and comfortable operation;
- Convenient access to all components simplifies and reduces the time for maintenance;
- The use of variable intensity technology reduces the load on mechanical elements;
- The applied manipulator carriage with mechanical grippers requires less attention, operator control and is more reliable to mechanical impacts;
- Real-time air pressure monitoring and equipment shutdown if compressed air pressure drops below a specified range;
- Air recovery — compressed air savings by returning part of the air after the bottle blowing process back to the system for subsequent use;
- The design of the heating units allows for the adjustment of the position of the heating lamps in the horizontal plane, depending on the preform configuration to ensure high-quality and uniform heating, and eliminates the need to connect the coolant to the heating unit reflectors, simplifying operation and maintenance (removal and installation of units);
- A 3-phase heating lamp power supply system is used, eliminating possible phase imbalances in the power supply network and reducing the overall power consumption of the machine by up to 20%;
- Individual control of each oven heating zone from the control terminal allows you to set the optimal preform heating temperature for blowing high-quality PET containers;
- Uniform heating of preforms due to their rotation and air convection as they pass through the heating oven;
- Cooling the preform neck as it passes through the heating oven prevents deformation of its neck part.
